TECHNICAL AREA

This application relates to the field of terminal technologies, in particular to a carrier plate which is used for a foldable terminal and a foldable terminal.

BACKGROUND

A foldable terminal can meet a user's needs on a large screen and avoid large volume and portability problems caused by the large screen, and is one of the current development trends in the terminal field.

The foldable terminal normally comprises a flexible screen. Since the flexible screen is relatively flexible, the surface flatness of the flexible screen is relatively low and a wavy pattern is likely to appear on a surface of the flexible screen. As a result, the quality of a displayed image is deteriorated.

For some related technologies, as in 2a and 2 B shown to improve the surface flatness of a flexible screen 1 a carrier plate 2nd on one side of the flexible screen 1 arranged to the flexible screen 1 to support. If the backing plate 2nd however, as in 2a shown is too thick, bending activity of the flexible screen 1 limited. As in 2 B shown is the mechanical strength of the too thin carrier plate 2nd inadequate if the carrier plate 2nd is too thin, although the bending activity of the flexible screen 1 is not limited, and the surface flatness of the flexible screen 1 cannot be improved effectively if the carrier plate 2nd is too thin.

SUMMARY

This application provides a carrier plate for a foldable terminal and a foldable terminal that can improve the surface flatness of a terminal without restricting the bending activity of the terminal.

In order to achieve the above object, the following technical solutions are used in this application.

According to a first aspect, this application provides a carrier plate. The carrier plate comprises at least one flexible region, in which at least one flexible region a plurality of gaps are arranged, each gap has at least one opening, and the orientation of at least one opening in each gap corresponds to the bending direction of a flexible region in which the gap is located. In this way, when the carrier plate is applied to a terminal, it is on one side of a flexible screen which is contained in the terminal. When the flexible portion of the backing plate is bent, the gap can absorb the stress generated during bending and does not limit the bending activity of the terminal. In addition, in an area other than the gap area in the flexible area of the support plate, the mechanical strength of the flexible area of the support plate can be improved, so that a part of the flexible display screen corresponding to the flexible area of the support plate can be better supported, as a result helps improve the flatness of an entire surface of the terminal.

With regard to the first aspect, in a first possible implementation the gap passes through two opposite primary surfaces of the flexible region of the carrier plate. In this way, the gap can have the ability to absorb stresses relatively strongly, which more effectively ensures that the bending activity of the flexible region is not limited when the flexible region of the carrier plate is bent. In addition, the gap can make it possible to bend the flexible region of the carrier plate in two directions.

With regard to the first aspect, in a second possible embodiment the gap is a groove which is arranged in the flexible region of the carrier. In this way, the flatness of the primary surface, which is located in the carrier plate and is opposite the opening of the gap, is improved, so that the surface flatness of the flexible region is further improved, while at the same time ensuring that the bending activity of the flexible region is not restricted .

With regard to the second possible embodiment of the first aspect, in a third possible embodiment, the gap comprises a bottom surface and an inner side wall surface, and there is a smooth transition between the bottom surface and the inner side wall surface. In this way, stress concentration at a corner position where the inner side wall surface intersects with the bottom surface is avoided, which contributes to improving the life of the carrier plate.

With regard to the second possible embodiment of the first aspect, in a fourth possible embodiment, the ratio of a gap depth to a thickness of the carrier plate is between 77/80 and 97/100. Such a size ratio helps to further improve the surface flatness of the flexible area, ensuring that the bending activity of the flexible area is not restricted.

Each gap is a strip shape that contributes to the improvement of the mechanical strength of the flexible area and can absorb the stresses that arise during bending. Alternatively, each gap is a circular or elliptical hole shape that helps improve the mechanical strength of the flexible area, avoids stress concentrations at a corner of the inner side wall surface of the gap, and improves the life of the backing plate. Alternatively, each row of columns includes at least one band-shaped gap and a plurality of circular or elliptical hole-shaped columns, and at least one circular or elliptical hole-shaped column is separated on two sides of each gap, to improve the mechanical strength of the flexible area contributes, which better absorbs the stress generated during bending, avoids the stress concentration at a corner of the inner side wall surface of the gap and improves the service life of the carrier plate.

These components can communicate with each other using one or more communication buses or signal cables (not in 1 shown). A skilled person can understand that the in 1 hardware structure shown no restriction for the mobile phone 100 represents. The mobile phone 100 may contain more or fewer components than in 1 shown, or combine some components or have other component arrangements.

The following are the components of the cell phone 100 with reference to 1 described in detail.

The processor 101 is a control center of the mobile phone 100 . The processor 101 is with different components and lines with all components of the mobile phone 100 connected and performs various functions of the mobile phone 100 out and processes data by putting one in memory 103 stored registration program (app for short) executes or processes and that in memory 103 stored data. In some embodiments, the processor 101 contain one or more processing units. For example, the processor 101 be a Kirin 960 chip from Huawei.

The high frequency circuit 102 can be configured to receive and transmit a radio signal in an information receiving and sending process or in a paging process. In particular, the high-frequency circuit 102 Data received from a base station and then the data for processing to the processor 101 send. In addition, the radio frequency circuit transmits 102 associated uplink data to the Base station. The radio frequency circuit usually includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, and the like. In addition, the radio frequency switching 102 also communicate with another device via wireless communication. Wireless communication can be implemented using any communication standard or protocol, including but not limited to a global system for mobile communication, a general packet radio service, Code Division Multiple Access, Wideband Code Division Multiple Access, Long Term Evolution, one E-mail, a short message service and the like.

The memory 103 is configured to store a registration program and data. The processor 101 performs various functions of the mobile phone 100 out and processes data by using the registration program and the data stored in memory 103 saved. The memory 103 mainly comprises a program storage area and a data storage area. An operating system and a registration program which are required for at least one function (for example a sound or image reproduction function) can be stored in the program memory area. Data (e.g. audio data and a telephone book) can be stored in the data storage area when using the mobile phone 100 arise. In addition, the memory 103 high-speed random access memory and non-volatile memory such as magnetic disk memory, flash memory, or other volatile solid-state memory. The memory 103 can store various operating systems, such as an iOS operating system developed by Apple and an Android operating system developed by Google.

The touchscreen 104 can be a touchpad 104-1 and a screen 104-2 contain. The touchpad 104-1 can detect a touch event by a user of the cell phone 100 on or near the touchpad 104-1 is performed (e.g. an operation that the user does on the touchpad 104-1 or near the touchpad 104-1 with a suitable object such as a finger or a pen), and the sensed touch information to another component such as the processor 101 send.

The touch event that the user is near the touchpad 104-1 can be called a floating touch. The free touch can mean that the user does not have to touch the touchpad directly to select, move or drag an object (e.g. an icon), but that he only has to be near the terminal to do one perform the desired function. In a "floating touch" registration scenario, terms such as "touch" and "contact" do not implicitly refer to the direct touch of the touch screen, but to a touch near or near the touch screen.

Specifically, two capacitive sensors, a counter-capacitance sensor and a self-capacitance sensor, can be on the touchpad 104-1 to be ordered. The two capacitive sensors can alternate on the touchpad 104-1 to be ordered. The counter capacitance sensor is configured to implement a normal conventional multi-point touch, ie to recognize a gesture when the user touches the touchpad 104-1 touched. The self-capacitance sensor can generate a signal that is stronger than that of the mutual capacitance to detect a fingerprint farther from the touchpad 104-1 is removed. So when a user's finger hovers over a screen, the cell phone can 100 recognize a gesture by the user on the screen, for example at a location 20 mm above the touchpad 104-1 lies because the signal generated by the self-capacitance sensor is stronger than the signal generated by the counter-capacitance sensor.

Optionally, the touchpad 104-1 that can support the floating touch can be implemented in a capacitive type, an infrared light sensor type, an ultrasonic wave type, or the like. In addition, the touchpad 104-1 can be implemented in a variety of types, e.g. B. a resistive type, a capacitive type, an infrared type and a surface acoustic wave type. The screen 104-2 can be configured so that information entered by the user, information provided to the user and various menus of the mobile phone 100 are displayed. The screen 104-2 can be configured in the form of a liquid crystal display, an organic light-emitting diode or the like. The touchpad 104-1 can the screen 104-2 cover. After the touch event on or near the touchpad 104-1 the touchpad transmits 104-1 the touch event to the processor 101 to determine a type of touch event. Then the processor can 101 Depending on the type of touch event, a corresponding visual output on the screen 104-2 deliver.

Although the touchpad 104-1 and the screen 104-2 used as two independent components, the input and output functions of the mobile phone 100 in 1 can implement the touchpad 104-1 and the screen 104-2 be integrated to the input and Output functions of the mobile phone 100 implement in some embodiments.

One can understand that the touch screen 104 is formed by stacking materials from multiple layers. Only the touchpad (layer) and the screen (layer) are displayed in this embodiment of this application, and another layer is not included in this embodiment of this application. In addition, in some other embodiments of this application, the touch pad 104-1 the screen 104-2 cover, and a size of the touchpad 104-1 is larger than a size of the screen 104-2 so the screen 104-2 completely from the touchpad 104-1 is covered. Alternatively, the touchpad 104-1 on the front of the phone 100 can be configured in the form of a complete panel. In other words, every touch that the user has on the front of the cell phone 100 can be captured by the mobile phone. In this way, a complete touch experience can be realized on the front of the mobile phone. In some other embodiments, the touchpad 104-1 on the front of the phone 100 configured in a full panel form, and the screen 104-2 can also be on the front of the phone 100 can be configured in a full panel form. In this way, a frameless structure can be realized on the front of the cell phone.

In this embodiment of this application, the mobile phone can 100 additionally have fingerprint recognition. For example, on the back of the cell phone 100 (e.g. under a rear-facing camera) a fingerprint reader 112 configured, or on the front of the phone 100 (e.g. under the touchscreen 104 ) a fingerprint reader 112 can be configured. Another example is a fingerprint collector 112 that on the touch screen 104 can be configured to implement the fingerprint recognition function. In other words, the fingerprint collector 112 and the touchscreen 104 can be integrated to the fingerprint recognition function of the mobile phone 100 to implement. In this case, the fingerprint collector 112 on the touchscreen 104 configured and can be part of the touchscreen 104 be or on the touchscreen 104 can be configured in a different way. In addition, the fingerprint collection device 112 can also be implemented as a full screen fingerprint collector. Therefore, the touch screen 104 can be viewed as a panel on which fingerprint recognition can be performed at any location. The fingerprint collector 112 can send a collected fingerprint to the processor 101 send so the processor 101 processes the fingerprint (e.g. performs a fingerprint verification). A key component like the fingerprint collector 112 in this embodiment of this application is a fingerprint sensor. The fingerprint sensor can use any type of sensing technology, including but not limited to optical sensing technology, capacitive sensing technology, piezoelectric sensing technology, ultrasonic sensing technology, and the like.

The mobile phone 100 can also use the bluetooth device 105 included, which is configured so that it exchanges data between the mobile phone 100 and another end device with a short range (e.g. a cell phone or a smart watch). The bluetooth device 105 In this embodiment of this application, an integrated circuit, a Bluetooth chip or the like. be.

The mobile phone 100 can also have at least one sensor 106 included, such as a light sensor, a motion sensor or another sensor. In particular, the light sensor can contain an ambient light sensor and a proximity sensor. The ambient light sensor can control the luminance of the screen of the touch screen 104 adjust based on the brightness of the ambient light, and the proximity sensor can turn off the screen power when the phone is off 100 moved to an ear. As one of the motion sensors, an acceleration sensor can detect acceleration values in all directions (usually on three axes), can detect a magnitude and direction of gravity when the acceleration sensor is stationary, and can be used for an application for detecting the attitude of a mobile phone (e.g. switching between a cross - And a portrait screen, a related game and the calibration of the magnetometer posture), a function for detecting vibrations (such as a pedometer and a knock) and the like can be used. Other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer and an infrared sensor can be found in the cell phone 100 can be configured further. Details are not described here.

The Wi-Fi device 107 is configured to be for the mobile phone 100 provides network access that conforms to a standard Wi-Fi protocol. The mobile phone 100 can with the help of the Wi-Fi device 107 access a Wi-Fi access point to make it easier for users to receive and send email, browse a website, access streaming media, and the like. The Wi-Fi device 107 provides users with broadband wireless internet access. In some other embodiments can use the Wi-Fi apparatus 107 used as a wireless Wi-Fi access point and allow another device to access the Wi-Fi network.

The positioning device 108 is configured to have a geographic location for the mobile phone 100 provides. One can assume that the positioning device 108 specifically a receiver of a positioning system such as a global positioning system (GPS for short), a BeiDou navigation satellite system or a Russian GLONASS (GLOBAL NAVIGATION SATELLITE SYSTEM, global navigation satellite system). After receiving the geographic position sent by the positioning system, the positioning device transmits 108 the information for processing to the processor 101 or for storage in memory 103 . In some other embodiments, the positioning apparatus 108 alternatively, be a recipient of a supported global positioning system (assisted global positioning system, or AGPS for short). The AGPS system supports the positioning device 108 when implementing removal and positioning services as an assisted server. In this case, the server for the supported position determination communicates with the position determination device 108 (ie a GPS receiver) of a terminal such as the mobile phone 100 over a wireless communication network to assist with positioning. In some other embodiments, the positioning apparatus 108 positioning technology based on a Wi-Fi access point. Each Wi-Fi access point has a worldwide unique MAC address, and the terminal can scan and collect a broadcast signal from a surrounding Wi-Fi access point when Wi-Fi is enabled. Therefore, the terminal can get a MAC address sent from the Wi-Fi access point. The terminal sends the data (e.g., the MAC address) that can be used to specify the Wi-Fi access point to a site server over the wireless communication network. The location server obtains a geographical position of each Wi-Fi access point by retrieval, obtains a geographical position of the terminal by calculation based on the strength of the Wi-Fi broadcast signal, and sends the geographical position of the terminal to the positioning device 108 of the terminal.

The audio circuit 109 , a speaker 113 and a microphone 114 can have an audio interface between the user and the mobile phone 100 form. The audio frequency switching 109 can to the speaker 113 transmit an electrical signal into which the received audio data is converted, and the speaker 113 converts the electrical signal into a sound signal for output. The microphone also converts 114 the collected sound signal into an electrical signal. The audio circuit 109 receives the electrical signal, converts the electrical signal into audio data and outputs the audio data to the RF circuit 102 to send the audio data to another mobile phone, for example, or to send the audio data to the memory for further processing 103 out.

The peripheral interface 110 is configured to provide various interfaces for an external input / output device (e.g. a keyboard, a mouse, an external display, an external memory or a subscriber identity module card). The peripheral interface 110 is connected to the mouse, for example, via a universal serial bus interface (USB for short) and connected via a metal contact on a card slot of a subscriber identification module card to a subscriber identification module card (SIM) provided by a telecommunications operator. The peripheral interface 110 can be configured so that the external input / output peripheral device with the processor 101 and the memory 103 is coupled.

The mobile phone 100 can also the power supply 111 (e.g., a battery or a power management chip) that powers the components. The battery can logically with the processor 101 can be connected by using the power supply management chip, so that functions such as charging, discharging and power consumption management through the use of the power supply device 111 be implemented.

Although not in 1 shown, the mobile phone 100 also contain a camera (a front and / or a rear-facing camera), a flashlight, a micro-projection apparatus, a near-field communication apparatus (near-field communication, NFC for short) and the like. Details are not described here.

The end device, such as the mobile phone 100 , can be configured as a foldable device. The foldable device includes a flexible screen. Especially the one in the mobile phone 100 included touchscreen 104 is the flexible screen. For example, the flexible screen can be a flexible OLED screen (organic light-emitting diode, organic light-emitting diode), a flexible liquid crystal display (liquid crystal display, LCD for short) or another type of flexible screen.

For example, related to 9a to 9c , contains in some embodiments this registration if a terminal 200 is a mobile phone, the mobile phone is a flexible and a non-flexible area. In this way, the space occupied by the mobile phone when folded (as in 9c shown) takes, be relatively small to store and carry the mobile phone. When the mobile phone is in an unfolded state (as in 9a or 9b shown), the mobile phone can have a relatively large display area to make it easier for the user to operate and read the mobile phone.

In another example, this is based on 9d relates, the terminal 200 alternatively, in some other embodiments of this application, may also be a tablet computer. When the tablet computer is in a flexed state, part of the tablet computer can be placed horizontally and configured to display a keyboard to form an office work area, and the other part is inclined and configured to display an image or text to form an office display area for the user to perform mobile office work or game operation.

Another example that is based on 9e refers, is the terminal 200 which may alternatively be an electronic book in some other embodiments of this application. In this case, the electronic book is bent so that the electronic book can better simulate a book folding effect.

Since a flexible screen of a foldable terminal is relatively flexible and has a relatively low surface flatness, a flexible screen becomes 1 by placing a carrier plate 2nd on the back of a flexible screen 1 (ie an area facing the flexible screen 1 heard and opposite a display area) to improve the surface flatness of the terminal, as described in the background. If the backing plate 2nd however, is too thick, bending activity of the terminal is limited. If the backing plate 2nd is too thin, the surface flatness of the end device cannot be effectively improved.

As in 2c is shown, a relatively thick carrier plate is used in some related technologies 2nd arranged in a non-flexible area of a terminal and a relatively thin or no carrier plate in a flexible area of the terminal ( 2c shows a case in which no support plate is arranged in the flexible area). In this way, the flatness of the flexible area of the terminal can be effectively improved without restricting the bending activity of the flexible area of the terminal. However, since the support plate arranged in the flexible area of the terminal is relatively thin or no support plate is arranged at all, the surface flatness of the flexible area of the terminal cannot be effectively improved, and a problem such as a wave pattern still remains.

Note that the surface flatness of the flexible portion of the terminal is a degree of surface flatness when the flexible portion of the terminal is not bent, and a degree of surface smoothness when the flexible portion is curved. The smoothness depends on whether or not there is a wave pattern, roughness or the like on the surface when the flexible portion is bent. The wave pattern, roughness, or the like on the surface when the flexible area is bent is inversely proportional to a degree of surface smoothness and a surface flatness degree when the flexible area is bent. If, for example, as in 2d shown, when bending the flexible area of the terminal there is no wave pattern on the surface, the degree of surface smoothness and the degree of surface flatness when bending the flexible area are relatively high. As in 2e shown, the degree of surface smoothness and the degree of surface flatness are relatively low when the flexible area of the terminal is bent, when there are many wave patterns on the surface when the flexible area is bent.

Based on the above situation, as in 3a to 3d shown, an embodiment of this application offers a carrier plate 2nd and a terminal 200 . The carrier plate 2nd is on one side of a flexible screen 1 arranged in the terminal 200 is included. The carrier plate 2nd contains a flexible area, a variety of columns 3rd are in the flexible area of the carrier plate 2nd arranged, and the alignment of an opening of the gap 3rd corresponds to the bending direction of the flexible area. In this way, the gap 3rd when bending the flexible area of the carrier plate 2nd absorb the stress generated when bending the flexible portion, causing bending activity of the terminal 200 is not limited. In addition, an area (namely, a non-gap area 4th ) in the flexible area of the carrier plate 2nd that is not the area in which the gap 3rd located, the mechanical strength of the flexible region of the carrier plate 2nd improve so that part of the flexible screen 1 , the flexible area of the carrier plate 2nd corresponds, is better supported. If the backing plate 2nd also has an inflexible area, the inflexible area of the carrier plate 2nd a corresponding area of the flexible screen 1 base so that the surface flatness of the inflexible area of the terminal 200 is improved. This means that the entire surface flatness of the end device 200 improved without the bending activity of the end device 200 to limit.

For example, related to 9a to 9c , in some embodiments of this application, when the terminal 200 is a mobile phone, the support plate provided in this embodiment of this application is arranged on one side of a flexible screen of the mobile phone, so that both a flexible and a non-flexible area of the mobile phone can have a relatively high flatness when the mobile phone is in the fully deployed state (as in 9c shown). 9a) or in a half folded state (as in 9b shown) while the mobile phone can be bent. This avoids effects on the image display of the mobile phone and an operation carried out by a user on the mobile phone.

If the terminal 200 is a tablet computer, for example, in some embodiments of this application 9d The support plate provided in this embodiment of this application is arranged on one side of a flexible screen of the tablet computer, so that both a flexible region and a non-flexible region of the tablet computer have a relatively high flatness while the tablet computer is being bent can. If the tablet PC is used, for example, for the mobile office, an office operating area and an office display area of the tablet PC can have a relatively high flatness. This brings the user a relatively good office experience.

If the terminal 200 is an electronic book, for example, in some embodiments of this application an inflexible area of the electronic book can be used as the text display area (see 9e) . The carrier plate provided in this embodiment of this application is arranged on one side of a flexible screen of the electronic book, so that the text display area of the electronic book has a relatively high flatness, while ensuring that the electronic book has a relatively high book simulation effect. This can prevent a displayed text from being deformed because the text display area is bent, and improve the reading experience of the user.

Starting from the above basic application idea, the design variants of this application are described in detail below with reference to the associated drawings.

With reference to 3a to 3d once again an embodiment of this application, which is a carrier plate 2nd and a terminal 200 contains. The terminal 200 includes a flexible screen 1 , and the carrier plate 2nd is on one side of the flexible screen 1 arranged. The carrier plate 2nd includes at least one flexible area and there are multiple gaps in each flexible area 3rd arranged. Every crack 3rd has at least one opening, and a bending direction of at least one opening in each gap 3rd is the same as a bending direction of the flexible area in which the gap 3rd located so that when the carrier plate 2nd is bent in the direction of the bending direction, the gap 3rd in the carrier plate 2nd can absorb a stress generated by bending.

Referring to Figures 3a and 3b, the non-gap area has 4th the carrier plate 2nd a certain thickness (the thickness can be equal to the thickness of the non-flexible region of the carrier plate 2nd be) when the backing plate 2nd is in a non-bending state because of the flexible area of the carrier plate 2nd the gap 3rd and a non-gap area 4th includes. In this way, the non-gap area 4th the carrier plate 2nd to improve the surface flatness of the flexible area of the terminal 200 be used. In addition, the non-flexible area of the carrier plate 2nd a certain thickness and can be a corresponding area of the flexible screen 1 wear so that the surface flatness of the flexible area of the terminal 200 is improved.

With reference to 3c and 3d can if the carrier plate 2nd in the bent state, in the flexible area of the carrier plate 2nd the gap-free area 4th used to make the surface flatness of the flexible area of the terminal 200 to improve, and since the flexible area of the carrier plate 2nd the gap 3rd contains and the gap 3rd which can absorb stress generated when bending the flexible portion is a bending activity of the flexible portion of the terminal 200 not limited. In addition, the non-flexible area of the carrier plate 2nd a certain thickness and can be a corresponding area of the flexible screen 1 wear so that the surface flatness of the flexible area of the terminal 200 is improved.

In some embodiments, the flexible screen 1 a screen displayed on one side, which comprises a display surface and a rear surface opposite the display surface. As in 3a to 3d shown, in some embodiments of this application the carrier plate 2nd on a back of the flexible screen 1 arranged to the flexible screen 1 better support and cover one on the flexible screen 1 to avoid displayed image. In one possible version, the flexible screen 1 and the carrier plate 2nd by gluing, gluing, Welding or the like are firmly connected.

As in 4a to 4d shown, it is assumed that in a direction perpendicular to a display surface of the terminal 200 and two sides of the terminal 200 are respectively an A side and a B side (corresponding to the direction perpendicular to a main surface of the support plate 2nd are two sides of the carrier plate 2nd first and second page). A bending direction of the flexible area of the carrier plate 2nd is a direction D1 which is perpendicular to the display area of the terminal and faces the A-side of the terminal, or a direction D2 , which is perpendicular to the display area of the terminal and faces the B side of the terminal. For example, the terminal 200 a terminal device that is displayed on a page. The A side of the terminal 200 is a display surface and the B side is a rear surface. A bending direction D1 of the flexible area of the carrier plate 2nd is a bend direction to the display area, and a bend direction D2 of the flexible area of the carrier plate 2nd is a direction to the back surface (ie a direction opposite to the display surface).

For every flexible area of the carrier plate 2nd , in some embodiments, as in 4a and 4b shown, the flexible area has a bending direction D1 or D2 , ie the flexible area can be bent in one direction. In some other embodiments, such as in 4c and 4d shown, the flexible area has two bending directions D1 and D2 , ie the flexible area can be bent in a bidirectional manner.

With reference to 4a to 4d every gap has 3rd in this embodiment of this application at least one opening. One can assume that the gap 3rd has one or two openings.

As in 4a to 4c shown, the gap has 3rd an opening. The opening is on the A side or the B side of the terminal 200 facing, ie the opening is the direction of bending D1 or D2 facing the flexible area. In other words, the gap 3rd is a groove in the flexible area of the carrier plate 2nd is arranged. The gap 3rd does not go through two opposite primary surfaces a1 and a2 the carrier plate 2nd . In this case the depth is d of the gap 3rd less than the thickness of the carrier plate.

It should be noted that the depth d of the gap 3rd in this embodiment of this application a size of the gap 3rd in the direction perpendicular to the display area of the terminal 200 is. The depth d of the gap 3rd can be designed based on a bending radius of the flexible area. If the bending radius of the flexible area is relatively large, this means that the stress generated when bending the flexible area is relatively large, and the depth d of the gap 3rd can be designed relatively large to facilitate the absorption of more voltage. If the bending radius of the flexible area is relatively small, this indicates that the stress generated when bending the flexible area is relatively small and the depth d of the gap 3rd can be interpreted relatively small. Optionally, a ratio of the depth d of the gap 3rd to the thickness of the carrier plate 2nd are between 77/80 and 97/100. For example, the thickness of the carrier plate is 2nd 0.08 mm and the depth d of the gap 3rd 0.077 mm. Another example: the thickness of the carrier plate 2nd is 0.10 mm, and the depth d of the gap 3rd is 0.097 mm.

In addition, two opposite primary surfaces mean a1 and a2 the carrier plate 2nd in this embodiment of this application each that a surface of the support plate 2nd that with the flexible screen 1 is in contact, and a surface of the support plate 2nd , which is opposite to the aforementioned surface. The positions of the two main faces a1 and a2 are interchangeable.

With this construction, the gap 3rd absorb the stress generated when bending the flexible area, which effectively ensures that the bending activity of the flexible area is not restricted. It also has the non-gap area 4th (ie an area other than the area in which the gap 3rd a certain thickness in the bending area. This helps to improve the mechanical strength of the bending area. In addition, there is a primary surface that is on the support plate 2nd and not from the gap 3rd is traversed (ie a primary surface opposite the primary surface in which the opening of the gap 3rd located), a continuous surface. Between a bottom surface c of the gap 3rd and the primary surface that is not through the gap 3rd is passed, and that of the carrier plate 2nd , there is a carrier plate material with a certain thickness which helps to further improve the mechanical strength of the flexible region. On the premise that the bending activity of the terminal 200 is therefore not part of the flexible screen 1 , the flexible area of the carrier plate 2nd corresponds, better supported, to the surface flatness of the flexible area of the terminal 200 is improved and the overall surface flatness of the end device 200 will be improved.

Starting from a construction in which the gap 3rd has an opening, e.g. as in 4a shown when the openings of the column arranged in the flexible area 3rd to the A side of the terminal 200 can show the flexible area of the carrier plate 2nd be bent in one direction and the bending direction is Di. As in 4b shown, the flexible region of the carrier plate 2nd be bent in one direction if the openings in the columns 3rd , which are arranged in the flexible area, to the B side of the terminal 200 show, and the bend direction is D2. As in 4c are shown for the several columns arranged in the flexible area 3rd the openings of part of the column 3rd the A-side of the terminal 200 facing the openings of the other part of the column 3rd the B side of the terminal 200 , and two parts of the column 3rd are arranged alternately. Therefore, the flexible area of the carrier plate 2nd are bent bidirectionally, and the bending directions are D1 and D2. If the two parts of the column 3rd are arranged alternately, are the distances between any two adjacent columns 3rd equal. This helps parts of the flexible region to have a uniform stress absorption ability, so that the tension of the parts of the flexible region is uniform when the flexible region is bent.

As in 4d has shown the gap 3rd two openings. One of the two openings is on the A side of the terminal 200 there, i.e. in the bending direction Di, and the other towards the B side of the terminal 200 towards, i.e. in the direction of the bend D2 . In other words, the gap 3rd goes through two opposite primary surfaces a1 and a2 the carrier plate 2nd . In this case the depth is d of the gap 3rd equal to the thickness of the carrier plate 2nd .

Because the gap 3rd in this construction by the two opposite primary surfaces a1 and a2 the carrier plate 2nd is the ability of the gap 3rd absorbing the stress generated when bending the flexible portion higher, which can more effectively ensure that the bending activity of the flexible portion is not restricted. In addition, the non-gap area 4th a certain thickness in the bending area. This helps to improve the mechanical strength of the bending area. On the premise that the bending activity of the terminal 200 is not limited, therefore becomes part of the flexible screen 1 , the flexible area of the carrier plate 2nd corresponds, better supported, to the surface flatness of the flexible area of the terminal 200 is improved and the overall surface flatness of the end device 200 will be improved.

In addition, the flexible area of the carrier plate 2nd arranged so that the gap 3rd has two openings so that the flexible region of the carrier plate 2nd can be bent in two directions, and the bending directions are D1 and D2.

For a crack 3rd with an opening related to 5a to 5k , is a cross-sectional shape of the gap 3rd not limited to a shape such as a rectangle, a trapezoid, a U-like shape, a semicircle, a triangle, or an irregular shape. It should be noted that the cross-sectional shape of the gap 3rd described in this embodiment of this application relates to: a cross-sectional shape obtained after the gap 3rd cut along a longitudinal direction perpendicular to a flexible surface and perpendicular to a display surface of a terminal (corresponds to a direction perpendicular to the longitudinal direction of the flexible surface and perpendicular to the primary surface a1 or a2 the carrier plate 2nd ). For example, the cross-sectional shape of the gap 3rd , as in 3a shown a cross-sectional shape after cutting the gap 3rd is obtained along the cross-sectional line AA '. The longitudinal direction of extension of the flexible region is a direction parallel to a bending axis 00 ' of the flexible area. The longitudinal direction of the flexible region can be any direction parallel to a flat surface of the display surface of the terminal 200 be. For example, the longitudinal direction of the flexible portion is parallel to a horizontal direction of the image display or parallel to a vertical direction of the image display or an acute angle relative to the horizontal direction of the image display.

We still refer to 5a to 5k In one possible construction, an inner side wall surface b of the gap may be a flat surface, a stepped surface, an arc surface, a curved surface, a corrugated surface or the like. Note that the inner side wall surface b of the gap 3rd in this embodiment of this application an area is that of the gap 3rd corresponds to and the one side surface of the carrier plate 2nd opposite (namely another surface in the carrier plate 2nd than the two main faces a1 and a2 ).

For example, as in 5a shown a depth d of the gap 3rd equal to the thickness of the carrier plate 2nd . In other words, the gap 3rd runs through two opposite primary surfaces a1 and a2 the carrier plate 2nd . A cross-sectional shape of the gap 3rd is a rectangle, and the inner side wall surface b of the gap 3rd is a flat surface. This way the gap has 3rd two openings, one opening is on the primary surface a1 the carrier plate 2nd , the other opening is on the primary surface a2 the carrier plate 2nd , and the widths w of the two openings are the same. Because the gap 3rd through the two opposite primary surfaces a1 and a2 the carrier plate 2nd runs, the gap 3rd absorb more tension when bending. Because the two main surfaces a1 and a2 the carrier plate 2nd one opening each of the gap 3rd can have the flexible region in which the gap 3rd located, be bent in two directions. Since also the widths w of the two openings on the gap 3rd are equal, the bend radii of the bidirectional bend are on the bendable area where the gap is 3rd is the same.

It should be noted that the width w of the opening of the gap 3rd in this embodiment of this application a size of the gap 3rd in a direction of expansion perpendicular to a length of the flexible portion. The width w of the opening of the gap 3rd can be designed based on the bending radius of the flexible area. If the bending radius of the flexible portion is relatively large, it means that the stress generated when bending the flexible portion is relatively large, and the width w of the opening of the gap 3rd can be designed relatively large to facilitate the absorption of more voltage. If the bending radius of the flexible area is relatively small, this indicates that the stress generated when bending the flexible area is relatively small and the width w of the opening of the gap 3rd can be interpreted relatively small.

As in 5b a depth of the gap is shown, for example 3rd equal to the thickness of the carrier plate 2nd . In other words, the gap 3rd runs through two opposite primary surfaces a1 and a2 the carrier plate 2nd . A cross-sectional shape of the gap 3rd is a trapezoid, and the inner side wall surface b of the gap 3rd is a flat surface. This way the gap has 3rd two openings, one opening is on the primary surface a1 the carrier plate 2nd , the other opening is on the primary surface a2 the carrier plate 2nd , and a width w1 of one opening is larger than a width w2 of the other opening. Because the gap 3rd through the two opposite primary surfaces a1 and a2 the carrier plate 2nd runs, the gap 3rd absorb more tension when bending. Because the two main surfaces a1 and a2 the carrier plate 2nd one opening each of the gap 3rd can have the flexible region in which the gap 3rd be bent in two directions. Because the widths of the two openings on the gap 3rd are not the same, the bend radii of the bidirectional bend are on the flexible area in which the gap 3rd is not the same.

For example, as in 5c shown the depth of the gap 3rd equal to the thickness of the carrier plate 2nd . In other words, the gap 3rd runs through two opposite primary surfaces a1 and a2 the carrier plate 2nd . The cross-sectional shape of the gap 3rd is a shape that is created by superimposing two rectangles of different widths (namely the size of the rectangles in a direction parallel to the primary surface of the carrier plate 2nd ) arises, and the inner side wall surface of the column 3rd is a step surface. This way the gap has 3rd two openings, one opening is on the primary surface a1 the carrier plate 2nd , the other opening is on the primary surface a2 the carrier plate 2nd , and the width w1 of one of the openings is larger than the width w2 of the other opening. Because the gap 3rd through the two opposite primary surfaces a1 and a2 the carrier plate 2nd runs, the gap 3rd absorb more tension when bending. Because the two main surfaces a1 and a2 the carrier plate 2nd one opening each of the gap 3rd can have the flexible region in which the gap 3rd be bent in two directions. Because the widths of the two openings on the gap 3rd are not the same, the bend radii of the bidirectional bend are on the flexible area in which the gap 3rd is not the same.

In the 5b and 5c Constructions shown are on a device 200 Can be used with different bending radii of bidirectional bending in a flexible area. If, for example, the bending radii are in two bending directions D1 and D2 of the flexible region are α and β, respectively, and α is larger than β, this indicates that a stress caused by bending the flexible region in the direction of the bending direction D1 generated is greater than a stress caused by bending the flexible portion in the direction of the bending direction D2 is produced. Therefore, a width of an opening that the gap 3rd corresponds and the bending direction D1 facing is larger than a width of an opening that the bending direction D2 is facing so that the opening corresponds to the bending direction D1 facing, absorbs more tension.

In some possible constructions, if an inner side wall surface b of the gap 3rd a stepped surface in a direction perpendicular to the primary surface of the carrier plate 2nd is the inner side wall surface b of the gap 3rd not limited to containing only one level ( 5c shows that the side wall surface b contains a step), and the inner side wall surface b of the gap 3rd may also contain two or more stages. In other words, a cross-sectional shape of the gap 3rd is not limited to a shape formed after two rectangles of different widths are overlaid on each other, and may alternatively be a shape formed after two or more rectangles successively in the direction perpendicular to the primary surface of the support plate 2nd were placed on top of each other. The widths of the two or more rectangles are successively in the direction perpendicular to the primary surface of the support plate 2nd enlarged or reduced.

If in this embodiment of this application the depth of the gap 3rd equal to the thickness of the carrier plate 2nd is, the side wall surface b of the gap 3rd configured further than another structure will. In some embodiments of this application, the side wall surface is b of the gap 3rd arched, see 5d . In relation to 5e is the side wall surface b of the gap 3rd wavy in some other embodiments of this application.

For example, as in 5f shown a depth d of the gap 3rd less than the thickness of the carrier plate 2nd . In other words, the gap 3rd does not go through two opposite primary surfaces a1 and a2 the carrier plate 2nd . A cross-sectional shape of the gap 3rd is a rectangle, and the inner side wall surface b of the gap 3rd is a flat surface. This way the gap has 3rd an opening located on a primary surface of the carrier plate 2nd located. The main surface that is on the carrier plate 2nd and not from the gap 3rd is crossed is a continuous area. Therefore, the mechanical strength of the flexible area of the carrier plate 2nd be further improved so that the surface flatness of the flexible area of the terminal 200 is further improved.

As in 5g shown, for example, is a depth d of the gap 3rd less than the thickness of the carrier plate 2nd . In other words, the gap 3rd does not go through two opposite primary surfaces a1 and a2 the carrier plate 2nd . A cross-sectional shape of the gap 3rd is a trapezoid, and the inner side wall surface b of the gap 3rd is a flat surface. This way the gap has 3rd an opening, and the opening is on a primary surface of the carrier plate 2nd . Because an angle between the inner side wall surface of the gap 3rd and a bottom surface of the gap 3rd is an obtuse angle, ie in a direction perpendicular to the primary surface of the carrier plate 2nd runs and from the primary surface in which the opening of the gap 3rd located to the bottom surface of the gap 3rd shows, the width of the opening gradually decreases. Therefore, the gap 3rd Absorb stresses that arise when more flexible areas are bent.

If the depth of the gap 3rd in this embodiment of this application is less than the thickness of the carrier plate 2nd , the side wall surface b of the gap 3rd can be configured further than another structure. Related to 5h is the inner side wall surface b of the gap in some embodiments of this application 3rd ladder-like. In relation to 5i is the side wall surface b of the gap 3rd arcuate in some other embodiments of this application. In relation to 5j is the side wall surface b of the gap 3rd in still other embodiments of this application a waveform.

In one possible execution, based on 5k relates, is a smooth transition between the inner side wall surface b and a bottom surface c of the gap 3rd realized. The inner side wall surface b and the bottom surface c of the gap become optional at a cutting position e 3rd designed a rounded angle that can avoid stress concentration at a corner position where the inner side wall surface b intersects with the bottom surface c, for loss due to the fatigue strength of the support plate 2nd to reduce and the life of the carrier plate 2nd to improve.

For a crack 3rd with an opening related to 6a to 6e and 7a to 7c , is a planar surface shape of the gap 3rd not limited to a shape such as a stripe shape, a hole shape, a diamond shape or an irregular shape. It should be noted that the planar surface shape of the gap 3rd in this embodiment of this application a form of an orthographic projection (equivalent to an orthographic projection onto a primary surface a1 or a2 a carrier plate 2nd ) of the gap 3rd on a display area of a terminal. The shape of the planar surface of the gap 3rd can be used as a form of an opening of the gap 3rd be understood.

For example, the planar surface shape of the gap 3rd in some embodiments with reference to FIG 6a and 6b a stripe shape, and specifically may be a straight line stripe shape, a wavy line stripe shape, or the like. In a possible construction in which the planar surface shape of the gap 3rd the stripe shape is a longitudinal direction of expansion of the gap 3rd consistent with a longitudinal direction L of a flexible area in which the gap 3rd located. If the planar surface shape of the gap 3rd the band shape is, can also in the longitudinal direction L of the gap 3rd a width w of the gap 3rd remain constant or change. It should be noted that if the width w of the gap 3rd in the longitudinal direction of the gap 3rd changes, the width w of the gap 3rd to an average width of the gap 3rd relates.

In relation to 6c and 6d is the planar surface shape of the column 3rd in some other embodiments, a hole shape, for example, it can be a circular, elliptical or square hole shape. Especially when the planar surface shape of the gap 3rd is the circular hole shape or the elliptical hole shape, there is no corner or sharp corner on an inner side wall surface of the gap 3rd , which avoids a concentration of tension on the corner or the sharp corner, so that the gap 3rd Exerted tension is more uniform, which improves the life of the carrier plate 2nd contributes.

With reference to 6e are multiple columns in some embodiments of this application 3rd in the flexible area of the carrier plate 2nd are arranged a variety of columns 3rd , whose flat surface shapes are strip shapes, and several columns 3rd whose flat surface shapes are circular or elliptical hole shapes are included, as well as the multiple columns 3rd , which are arranged in the flexible area, arranged in several rows. Every row of columns 3rd contains at least one strip-shaped gap and a plurality of columns in a circular or elliptical hole shape, and at least one gap in a circular or elliptical hole shape is arranged separately on two sides of each strip-shaped gap. In this way it is ensured that the majority of the gaps arranged in the flexible region 3rd can absorb a relatively large amount of tension, but the tension concentration at a corner or a sharp corner of the inner side wall surface of the band-forming gap 3rd is reduced, causing the flexible area to break out of the band forming gap 3rd prevented after repeated bending and the life of the carrier plate 2nd improved.

For an area of a carrier plate that is only flexible in one direction 2nd who is on 7a to 7c , an arrangement pattern can consist of a plurality of gaps arranged in the flexible region 3rd can be arranged arbitrarily based on an actual need.

As in 7a are shown, for example, a plurality of strip-shaped columns parallel to one another 3rd arranged in the flexible area, and the longitudinal direction of each gap 3rd is parallel to a longitudinal direction of the flexible region. The depth of each gap is optional 3rd less than the thickness of the carrier plate 2nd , in other words, every crack 3rd is a groove in the backing plate 2nd is arranged in the flexible area. In addition, the column is between two adjacent columns 3rd in the majority of the column 3rd same size. In this way, the tension absorbed by each area in the flexible area becomes more uniform, resulting in bending activity of the terminal 200 better supported.

As in 7b are shown, for example, several rows of mutually parallel columns 3rd arranged in the flexible area, and each row contains a plurality of parallel strip-shaped columns which are spaced apart. The depth of each gap is optional 3rd equal to the thickness of the carrier plate 2nd . In other words, every crack 3rd runs through two opposite primary surfaces a1 and a2 of the flexible area of the carrier plate 2nd . They are also along one direction L ' perpendicular to the longitudinal direction of the flexible area several gaps 3rd that are in two adjacent rows of columns 3rd are included, offset, which contributes to improving the mechanical strength of the flexible area. This becomes part of the flexible screen 1 , the flexible area of the carrier plate 2nd corresponds, better supported and the surface flatness of the end device 200 improved.

As in 7c several rows of columns are shown, for example 3rd that are parallel to each other, arranged in the flexible area, and each row of columns 3rd contains several diamond-shaped columns 3rd that are spaced. An arrangement direction of the rhombic columns contained in each row 3rd is parallel to the longitudinal direction of the flexible area. The depth of each diamond-shaped gap is optional 3rd equal to the thickness of the carrier plate 2nd . In other words, every crack 3rd runs through two opposite primary surfaces a1 and a2 of the flexible area of the carrier plate 2nd . They are also along one direction L ' perpendicular to the longitudinal direction of the flexible area several diamond-shaped gaps 3rd that are in two adjacent rows of diamond-shaped columns 3rd are included, offset, which contributes to improving the mechanical strength of the flexible area. This becomes part of the flexible screen 1 that of the flexibility of the carrier plate 2nd corresponds, better supported and the surface flatness of the end device 200 improved.

In this embodiment of this application, the diamond-shaped gap 3rd be a standard diamond shape. The diamond-shaped gap 3rd can alternatively be similar to a shape of the standard diamond. To look up again 7c Coming Back: A shape that is an arcuate transition surface and resembles the standard diamond is placed at the sharp corners of the two ends of the standard diamond, causing stress accumulation at the sharp corners of the two ends of the diamond-shaped column 3rd can be avoided. In this way the breaking of the flexible area of the carrier plate 2nd after repeated bending of the flexible area avoided and the life of the carrier plate 2nd improved.

In addition, each row of gaps 3rd next to a complete diamond gap 3rd also a partial herb gap 3rd contain. For example, includes, again related to 7c , each row of columns 3rd half of the diamond-shaped column 3rd . This allows more gaps in the flexible area 3rd be arranged, which is the bending performance of the carrier plate 2nd further improved.

For example, are related to 6e , several rows of columns 3rd that run parallel to each other, in the flexible area arranged, and each row contains the multiple columns 3rd that are spaced. A direction of arrangement of the multiple columns 3rd which are contained in each row is parallel to the longitudinal direction of the flexible region. Each row contains at least one gap 3rd in strip form and several columns 3rd in a circular or elliptical hole shape, and at least one gap in a hole shape is arranged separately on two sides of each strip-shaped gap. Furthermore, the majority of the gap contained in each row 3rd the strip-shaped gap 3rd and the circular hole-shaped gap 3rd or the elliptical hole-shaped gap 3rd alternately spaced and two ends of an outermost side of each row are the circular hole-shaped gap 3rd or the elliptical hole-shaped gap 3rd . With this arrangement it is ensured that the multiple gaps arranged in the bending area 3rd can absorb a relatively large amount of tension, however, the tension concentration becomes at a corner or a sharp corner of the inner side wall surface of the band forming gap 3rd reduces what a breaking of the bending area from the band forming gap 3rd prevented after repeated bending and the life of the carrier plate 2nd improved.

Note that an arrangement density of the plurality of gaps 3rd in the flexible area of the carrier plate 2nd can be interpreted based on an actual need. If the bending radius of the flexible region is relatively large, this indicates that the stress generated when bending the flexible region is relatively large, and the arrangement density of the plurality of gaps 3rd can be designed relatively large to facilitate the absorption of more voltage. If the bending radius of the flexible area is relatively small, this indicates that the stress generated when bending the flexible area is relatively small and the arrangement density of the plurality of gaps 3rd can be interpreted relatively small.

In some embodiments, as in 5a and 5l shown contains a carrier plate 2nd also at least one non-flexible area, and the thickness h1 of a non-gap area 4th in a flexible area of the carrier plate 2nd is less than or equal to the thickness h2 of the non-flexible area of the carrier plate 2nd . With this construction, part of a flexible screen 1 that the inflexible area of the carrier plate 2nd corresponds, well supported, to the flatness of the flexible screen 1 to improve. Under the premise, the mechanical strength of the flexible area of the carrier plate 2nd To improve, the bending performance of the carrier plate can also be improved, so that the carrier plate 2nd has a relatively large bending angle.

As in 5a for example, the thickness h1 of the non-gap area is shown 4th in the flexible area of the carrier plate 2nd is equal to the thickness h2 of the non-flexible area of the carrier plate 2nd . In this way the mechanical strength of the flexible area 21st the carrier plate 2nd improved.

For example, as in 5l shown the thickness h1 of the non-gap area 4th in the flexible area of the carrier plate 2nd less than the thickness h2 of the non-flexible area of the carrier plate 2nd . In this way, under the premise of improving the mechanical strength of the flexible portion, the bending performance of the support plate can be improved, so that the support plate 2nd has a relatively large bending angle. Note that the thickness h1 of the non-gap area 4th can be thinned in the bending area in a manner that enables dry etching, wet etching or laser etching.

In the terminal provided in this embodiment of this application 200 is the multitude of columns 3rd in the flexible area of the carrier plate 2nd arranged to when bending the terminal 200 to absorb generated voltage. In this way, even with a relatively large thickness of the carrier plate, it can be ensured that the end device bends 200 is not limited. Therefore, the thickness of the carrier plate 2nd be appropriately increased without the bending activity of the terminal 200 limit to the mechanical strength of the carrier plate 2nd further increase, so that the carrier plate the surface flatness of the terminal 200 can improve better. The thickness of the carrier plate is optionally greater than 0.05 mm. In addition, the thickness of the carrier plate 2nd greater than 0.05 mm and less than or equal to 0.5 mm.

In this embodiment of this application, the column 3rd in the carrier plate 2nd processed in different ways. In some versions, the gap 3rd by removing the material of part of the column to be formed 3rd in the carrier plate 2nd be generated. For example, the gap 3rd are manufactured by a method such as laser etching, plasma etching or wet etching. The tension at each position of the carrier plate 2nd which is achieved by the production in this way is uniform and the surface flatness is high.

In relation to 10th may be a backing plate in some other embodiments 2nd can be produced by superimposing several layers of base materials. For example, first a base material 21st and then a second base material 22 on a side surface of the first base material 21st placed. The second base material 22 includes a cavity f1 and a non-hollow area f2. The cavity f1 corresponds to an area in the carrier plate 2nd A gap 3rd is to be formed, and the non-hollow area f2 corresponds to a non-gap area 4th in the carrier plate 2nd . The second base material 22 is in the area where the gap 3rd in the carrier plate 2nd is to be hollowed out so that a thickness of the area in which the gap 3rd the carrier plate 2nd to be formed, a thickness of the first base material 21st is. The second base material 22 becomes in the non-gap area 4th the carrier plate 2nd not hollowed out, so a thickness of the non-gap area 4th in the carrier plate 2nd a thickness of a carrier plate to be molded 2nd reached, causing the carrier plate 2nd with a required gap 3rd is formed. The gap created in this way 3rd the carrier plate 2nd is a crack 3rd with an opening, ie a gap 3rd that is not through two primary surfaces of the carrier plate 2nd runs. In addition, the tension is at every position of the carrier plate 2nd which is achieved by the production in this way, evenly and the surface flatness is high. The first basic material 21st and the second base material 22 can be connected to one another by gluing, diffusion molding or the like.

In addition, in some other embodiments, the gap 3rd alternatively, they can also be produced using a different processing method. So the gap 3rd for example by roll forming or mechanical cutting. Details are not described here again individually.

In this embodiment of this application, any material with a specific mechanical strength can be used as the material of the carrier plate 2nd to get voted. Optionally, the material of the carrier plate can be a material with high mechanical strength, good surface flatness and strong bending performance. For example, the backing plate 2nd a metal backing plate. In addition, the carrier plate 2nd a stainless steel carrier plate or a copper carrier plate.

With reference to 3a to 3d In some embodiments of this application, the carrier plate can be used in addition to at least one flexible area 2nd further comprise at least one non-flexible area, and the non-flexible area is connected to the flexible area. The thickness of the non-flexible area corresponds to the thickness of the non-cleavable area 4th in the flexible area. This way you can also use a part of a flexible screen 1 , the non-flexible area of the carrier plate 2nd corresponds, well supported, which is the flatness of an entire display area of the terminal 200 improved.

In this embodiment of this application, there can be a variety of bending forms of the terminal 200 give, and a design of the gap in the carrier plate 2nd must meet a requirement for an appropriate bending shape. With reference to 8a to 8f Below are several bending shapes and possible designs of a gap in a corresponding carrier plate 2nd described.

For example, the backing plate 2nd of the terminal 200 , related to 8a , a flexible area, and the flexible area can be bent in one direction D1 or D2 to be bent (in 8a is the bending direction of the flexible area D1 ). In this case, to ensure that there is bending activity on the end device 200 is not limited to multiple columns 3rd arranged at a distance in the flexible region of the carrier plate. Every crack 3rd can use a structure through the two primary surfaces a1 and a2 the carrier plate 2nd cannot be passed through. An opening in each gap 3rd is a bending direction of the end device 200 facing.

For example, the backing plate 2nd of the terminal 200 , related to 8b , a flexible area, and the flexible area can be in the direction of the bending direction D1 and D2 be bent. So that the bending activity of the terminal 200 in this case, the multiple columns are not limited 3rd arranged at a distance in the flexible region of the carrier plate. Every crack 3rd can use a structure through the two primary surfaces a1 and a2 the carrier plate 2nd be passed through. Two openings in each gap 3rd lie separately in two bending directions of the end device 200 .

Related to 8c has, for example, the carrier plate 2nd of the terminal 200 two flexible areas, and one of the flexible areas can face the direction of the bend D1 be bent (e.g. a second flexible area in 8c ), another flexible area can go in the direction D2 be bent (e.g. a first flexible area in 8c ). In this case, to ensure that the bending activity of the terminal 200 not limited, can be in the flexible area in which the carrier plate 2nd in the direction of the bend D1 can be bent, any gap 3rd use the structure that two primary surfaces a1 and a2 the carrier plate 2nd not be run through and the opening of each gap 3rd in the bending direction D1 lies. Any gap can also 3rd in the flexible area in which the carrier plate 2nd in the direction of the bend D2 can be bent, use the structure that two primary surfaces a1 and a2 the carrier plate 2nd not be run through and the opening of each gap 3rd the bending direction D2 is facing.

For example, the backing plate 2nd of the terminal 200 , related to 8d , two flexible areas, and a bending radius of one of the flexible areas is larger than a bending radius of another flexible area. That way it can Terminal 200 be bent when folded. In this case, the bending radius of one of the flexible areas may be larger than the bending radius of the other flexible area by using parameters such as area of the flexible area, a number of columns 3rd in the flexible area, an arrangement density of the columns 3rd in the flexible area, a direction of opening of the gap 3rd , a depth of the gap 3rd and a width of the gap 3rd be designed.

Related to 8e are, for example, all or most parts of the carrier plate 2nd of the terminal 200 flexible areas. The terminal 200 can be bent while scrolling, and the terminal 200 can form a shape similar to the shape of a scroll when the terminal 200 is bent when scrolling. From one end of the carrier plate 2nd , which is in the middle of the roll, up to an end which is on the outermost side of the roll, the bending radius of the flexible region of the carrier plate takes 2nd gradually decrease. In this case the bending radius of the flexible area of the carrier plate increases 2nd from the center of the snail to the outermost side of the snail gradually decrease by parameters like a number of columns 3rd in the flexible area, an arrangement density of the column 3rd in the flexible area, a direction of opening of the gap 3rd , a depth of the gap 3rd and a width of the gap 3rd be designed.

Related to 8f are, for example, all or most parts of the carrier plate 2nd of the terminal 200 flexible areas. The terminal 200 can be bent smoothly, and that the terminal 200 is smoothly curved, resembles the movement of a chain in a wheel. Parts of the flexible areas of the carrier plate can be bent in the same bending radius. In this case, the bending radii of parts of the flexible areas of the carrier plate 2nd be the same by using parameters like a number of columns 3rd in the flexible area, an arrangement density of the columns 3rd in the flexible area, a direction of opening of the gap 3rd , a depth of the gap 3rd and a width of the gap 3rd be designed.

It should be noted that in this embodiment of this application, a bending shape of the terminal 200 is not limited to the above several types. A variety of other bending shapes can be provided by designing a cross-sectional shape, a flat surface shape, a depth, a width, an arrangement pattern, an arrangement density and the like of the gap in the carrier plate 2nd and by designing and combining a set of flexible portions, a set of non-flexible portions, a portion of the flexible portion, a bending radius of the flexible portion, a longitudinal direction of extension of the flexible portion, and the like in the carrier plate 2nd will be realized. Details are not described here again individually.

It should also be noted that in the terminal provided in this embodiment of this application 200 when the terminal 200 after bending into a flat surface condition is unfolded because of the gap 3rd in the flexible area of the carrier plate 2nd is arranged and the gap 3rd through the backing plate 2nd can release tension generated completely and thoroughly in a bending process, so that in the unfolded carrier plate 2nd less tension remains, or even no tension remains, which is the problem of internal stress and the accumulation of the carrier plate 2nd avoids bending and then unfolding, solves the problem that the terminal is deformed and arched due to the problem of internal stress and the accumulation of the carrier plate 2nd after bending and then unfolding is caused, and the flatness of a surface after bending and then unfolding the terminal 200 improved. It can be learned that not only the flatness of an entire surface of the device 200 , which is provided in this embodiment of this application, is high, but also the bending activity is not limited. In addition, the surface is in a state after the bending and subsequent unfolding of the terminal 200 not arched, and the flatness is also relatively high. Therefore, there is an image display effect of the terminal 200 relatively good in the two aforementioned conditions.

The foregoing descriptions are only specific implementations of this application, but are not intended to limit the scope of this application. Any change or replacement within the technical scope disclosed in this application falls within the scope of this application. The scope of this application is therefore subject to the scope of the claims.
